(21e) Evaluating Different Methods Used to Manufacture Particleboards Produced Using the Blend of Plant Waste From Industrial Processes and Different Resins

Solid wastes from industrial processes have the potential of polluting groundwater, the atmosphere, and soils. This makes its final disposal a major environmental concern. A valuable service would therefore be to find alternative uses for this waste. In this work plant waste generated by the industry was used to produce particleboards. Two types of panels were produced. The first used the blend of waste from Cumaru (Dipteryx odorata) and polyurethane resin. The second used the blend of waste from wood of Eucalyptus (Eucalyptus sp.), asparagus (Asparagus officinalis), sugar-cane (Saccharum officinarum), and urea-formaldehyde (UF) resin. Physical-mechanical properties of the particleboards, including modulus of rupture, strength, modulus of elasticity, and perpendicular traction, were evaluated following the EN and the ASTM norms. The results obtained in this work were satisfactory. The values found were compatible to those found in the literature and in commercial standards. Thus, this experimental work demonstrated the potential use of renewable resource to produce panel for the civil industry.
